I am using Wix 3.11.1 with VS2017 Extension. I set a property from a control on a custom Dialogue and then try to execute an immediate custom action. When I try to read the session, it is always empty.
As recommended I changed my action to differed execution and used an immediate action to set my property. When I run my installer I get the error: "DEBUG: Error 2896: Executing action [ActionName] failed."
In CustomDialog.wxs
<Control Id="ConnId" Type="Edit" X="60" Y="110" Height="17" Width="300" Property="CONN"/>
<Control Id="installButton" Type="PushButton" Text="Continue" Height="15" Width="60" X="240" Y="260">
<Publish Event="DoAction" Value="RegistrationInfoCustomAction">1</Publish>
<Publish Event="EndDialog" Value="Return">1</Publish>
</Control>
<Fragment>
<Binary Id="CustomActionBinary" SourceFile="..\..\CustomActions\bin\Debug\CustomActions.CA.dll"/>
<CustomAction Id="SetPropertyForShowProperty" Property="RegistrationInfoCustomAction" Execute="immediate" Value="[CONN]" Return="check" />
<CustomAction Id="RegistrationInfoCustomAction" BinaryKey="CustomActionBinary" DllEntry="SaveUserInfo" Execute="deferred" Return="check" HideTarget="no"/>
</Fragment>
In Product.wxs
<InstallExecuteSequence>
<Custom Action="SetPropertyForShowProperty" After="InstallInitialize"/>
<Custom Action="RegistrationInfoCustomAction" Before="InstallFinalize"/>
</InstallExecuteSequence>
In CustomActions.cs
[CustomAction]
public static ActionResult SaveUserInfo(Session session)
{
Debugger.Launch();
CustomActionData data = session.CustomActionData;
session.Log("Begin SaveUserInfo");
var connectionString = data["CONN"];
session.Log($"content: {connectionString}");
session.Log("End SaveUserInfo");
return ActionResult.Success;
}
The custom action works when it contains only logging statements but adding any other code make it fail. Also, the session is always empty.

Similar Answers: I want to add some linkes to previous answers on the topic of deferred mode custom actions. There are links to github-samples in these answers - including one sample which uses the DTF class CustomActionData to easily send properties to deferred mode (once you are properly set up):
UPDATE: It is late, I didn't see this on first sight, but only immediate mode custom actions can be run from the setup GUI. Make a new, immediate mode custom action to set a value to your PUBLIC property CONN, and then set the value of CONN via a type 51 custom action to be assigned to the Id of the deferred mode custom action - as described below.
SecureCustomProperties: Add the property you specify to SecureCustomProperties by setting the Secure="yes" attribute:
<Property Id="MYPROPERTY" Secure="yes">Send this text to deferred mode</Property>
Name Match: the property name you assign the value to must match the deferred mode custom action Id. Looks OK in your source.
More Technical: the Property attribute's value
of the type 51 action
must be identical to the Id of the custom action that is consuming CustomActionData
:
<!-- Declare property with value -->
<Property Id="MYPROPERTY" Secure="yes">Send this text to deferred mode</Property>
<!-- Type 51 CA: Send value of MYPROPERTY to the deferred mode CA named MyAction -->
<CustomAction Id="MyAction.SetProperty" Return="check" Property="MyAction" Value="[MYPROPERTY]" />
<!-- The deferred mode custom action -->
<CustomAction Id="MyAction" Return="check" Execute="deferred" BinaryKey="CAs" DllEntry="MyAction" />
<!-- ... -->
<!-- Inserting the CAs in sequence -->
<InstallExecuteSequence>
<Custom Action="MyAction.SetProperty" After="InstallInitialize" />
<Custom Action="MyAction" Before="InstallFinalize" />
</InstallExecuteSequence>
Here are some resources:
Just for debugging reference. And you can use: string data = session["CustomActionData"];
Tell you what, let me slide in the code to test using VBScript so you can use message boxes. Should not be necessary, just in case you have a debugging issue:
VBScript "Simple.vbs"
(save as file):
MsgBox Session.Property("CustomActionData")
WiX markup change:
<Binary Id='Simple.vbs' SourceFile='Simple.vbs' />
<CustomAction Id="MyAction" Return="check" Execute="deferred" BinaryKey="Simple.vbs" VBScriptCall='' />
Just in case that is easier. Recommend you use VBScript for debugging only. I like VBScript to get a "heartbeat
" when I want to eliminate all other error sources.
